摘要: A battery case shaping apparatus includes a punch, a die, a holder, and an elastic separator. The punch is configured to press a laminate sheet into a shape of an electrode assembly receiving portion. The die has formed therein an accommodation portion having a size corresponding to the electrode assembly receiving portion. The holder is configured to fix the an outer periphery of the laminate sheet. The elastic separator is located under the punch in order to prevent direct contact between the punch and the laminate sheet. A battery case manufacturing process uses the battery case shaping apparatus to manufacture a battery case.

摘要: The present disclosure relates to a battery module including a busbar structure for adhesion with an electrode lead. The battery module can include a battery cell stack having a plurality of stacked battery cells, electrode leads protruding from the battery cell stack, a busbar electrically connected to the electrode leads, and a busbar frame on which the busbar is mounted. The busbar can be formed of a tongs part and a fixing part for connecting and fixing the tongs part. The electrode leads can be mounted between the tongs part of the busbar. The battery module can be manufactured through the steps of mounting a busbar in an opening part of a busbar frame, inserting an electrode lead between the tongs part of the busbar, closely adhering the busbar and the electrode lead through a jig, and removing the jig.
